The first flight of my model almost turned into fatality. First had to use quite a bit trim down on elevators to keep it at level flight, the plane turned out to be tail heavy, something I didn´t notice with my balance tool ( My fingers, big mistake). Second, had to use a lot of left trim on ailerons to keep it from banking to the right, this I believe could be caused because the fin/rudder seems to be pointing slightly to the right , the engine is mounted horizontaly at 90 degrees, and with some degree of offset to the right as per instructions, so this may not be the cause.
Rebalance its easily corrected replacing the battery and rx, but I´m thinking surgery on the Fin/rudder to correct the right bank tendency.
Any other suggestions and corrections of experiences as this one are greatly appreciated.

Thanks
